摘　　要：在P2P系统中,为高效地定位资源节点,提高系统性能,在分析经典Chord算法的基础上,通过扩展Chord路由表,提出一种新的路由算法,该算法能够减少转发次数,缩短搜索路径的长度及搜索延迟。仿真实验结果表明,该算法继承了经典Chord算法简单、高效、可靠、负载平衡及开销少的优点,提高Chord的查找效率。In order to locate the resource key with high efficiency and improve the system’s capability in P2P system,a new Chord algorithm by extending the finger table on basis of deep analysis of Chord is presented.This algorithm has lower latency and shorter search path than Chord.Simulation results indicate this algorithm inherits the advantages of Chord,such as simplicity,efficiency,reliability,load balance and low cost.So it gets higher search efficiency than original Chord.
